Real Names: Robert L. Frank, Sr. & Madeline Joyce-Frank
First Appearances: U.S.A. Comics (Vol. 1) #1, August 1941 (Whizzer, Timely Comics); Marvel Mystery Comics (Vol. 1) #49, November 1943 (Ms. America, Timely Comics); Giant-Size Avengers (Vol. 1) #1, August 1974 (first modern appearance for both)
Powers: Robert Frank was bitten by a poisonous snake and received a transfusion of mongoose blood that saved his life. His wife, Madeline, was struck by an electrical discharge. These separate incidences affected their physiologies to activate their apparently latent mutant powers.
The Whizzer possessed the ability to move at superhuman rates of speed. He possessed superhuman strength primarily in his lower body as part of his body's adaptations for running. With his upper body he could lift slightly more than a normal human being of his age, height, and build who engaged in intensive regular exercise could. In his prime, the Whizzer could leg press approximately 1500 pounds under optimal conditions and could run at speeds of up to 100 miles an hour for up to an hour before fatigue impaired his performance. With middle age, however, the Whizzer's ability to move at superhuman speed was diminished considerably.
The Whizzer's entire body was adapted for the rigors of high speed running. His cardiovascular and respiratory systems were many times more efficient than those of a normal human being's. He metabolized an estimated 75% of the caloric energy content of foodstuffs (normal human use is about 25%). The chemical processes of the Whizzer's metabolism were so highly enhanced that his body generated unusually low amounts of fatigue poisons, the normal by-products of locomotion which force the body to rest. His joints were smoother and were lubricated more efficiently than those of an ordinary human being's. His tendons had the tensile strength of spring steel. His bones contained unknown materials significantly more durable than calcium to withstand the dynamic shocks of his feet touching the ground at speeds of up to 100 miles per hour.
The Whizzer's practical reaction time was about four times faster than an ordinary human being's when the Whizzer was in his prime, and the speed at which his brain processed information was heightened to a level commensurate with his bodily speed, enabling him to perceive his surroundings while traveling at high velocities. The Whizzer's lachrymose was more viscous than a normal human being's, thus preventing rapid evaporation and replenishment of surface fluids on his eyeballs under the influence of high wind velocity to occlude his vision.
Miss America had the ability to psionically negate the effect of gravity around herself, allowing her to levitate into the air. In coordination with planned jumps, she could simulate the power of flight. She could attain any height at which she could still breathe (approximately 20,000 feet). She could use her power for up to two hours before mental fatigue would force her to rest. Also, fatigue poisons accumulated in her body much slower than that of a normal human, giving her a heightened vitality. Prior to her modern* appearance, she demonstrated superhuman strength, endurance, invulnerability, x-ray vision, and flight.
